Abstract
The invention relates to an angle type drain valve. The angle type drain valve comprises a handle component, a support component and a valve component, wherein a packing box component is arranged between the support component and the valve component; the packing box component is internally provided with a valve rod; the top end of the valve rod is connected with the handle component by the support component; the bottom end of the valve rod is provided with a valve rod sealing surface matched with a valve component fluid inlet sealing surface; the valve rod and the valve rod sealing surface are controlled by the support component and the handle component; the valve rod sealing surface and the valve component fluid inlet sealing surface are tightly compressed so that the valve is closed; and the valve rod sealing surface and the valve component fluid inlet sealing surface are separated so that the valve is opened. With the adoption of the angle type drain valve, the direct scouring of a high-speed fluid and residues is avoided; and at the same time, an eddy zone with a pressure more than that of the fluid centre is generated when the high-speed fluid flows near a socket close to the valve sealing surface, and the eddy zone is more in favour of preventing the high-speed fluid from closing to the valve sealing surface, so that the scouring of the high-speed fluid and the residues on the valve sealing surface is further avoided.
Description
Technical field
The present invention relates to valve, refer in particular to the angie type blowdown valve that industries such as a kind of suitable oil, chemical industry, thermoelectricity are used.
Background technique
Present blowdown valve is because valve rod is identical with the sealing configuration and the stop valve of valve seat, when valve open; Valve rod and seat portion form little gap; High-velocity fluid carries dregs, and the sealing surface of valve rod and valve seat is caused strong washing away, and also is like this when closing; Cause sealing surface to be destroyed, shorten the working life of valve.
Summary of the invention
The objective of the invention is to improve and innovate, the angie type blowdown valve of a kind of novel structure, protection against erosion, long service life is provided to the defective that exists in the background technique and problem.
Technological scheme of the present invention is a kind of blowdown valve that comprises Handleset, bracket component and valve component of structure; The Stuffing box assembly wherein is set between bracket component and the valve component; In the Stuffing box assembly valve rod is set; Valve stem tip connects Handleset through bracket component, and the bottom is provided with the valve stem seal face that coincide with valve component fluid inlet sealing surface, and valve rod and valve stem seal face are through bracket component and Handleset control; Valve stem seal face and valve component fluid inlet sealing surface compact throttle down, the valve stem seal face separates Open valve with valve component fluid inlet sealing surface.
Advantage of the present invention and beneficial effect:
The effect of valve rod front end cylindricality throttling bodies of the present invention; Be to make valve in opening procedure, two sealing surfaces that valve body that valve is former when closing and valve rod combine, have only when they in relative separation behind a segment distance; Be after the cylindricality throttling bodies breaks away from the fluid inlet passage of valve body fully; Valve is only opening state, and at this moment the sealing surface of valve rod is away from the outlet of valve body fluid inlet passage, and is positioned at passage place, large-section; This moment, flow rate of fluid was relatively low here, the valve stem seal face was washed away greatly reduce.Otherwise the valve closing process too, and therefore valve rod front end cylindricality throttling bodies plays the effect that postpones to open or shift to an earlier date closing valve in this blowdown valve, avoids high-velocity fluid and the slag high speed souring to the valve stem seal face.Valve body sealing surface is because of relatively away from the high-velocity fluid channel outlet; Effectively avoided directly washing away of high-velocity fluid and slag; Near the valve body sealing surface nest groove is when high-velocity fluid flows through near the nest groove simultaneously; Generation is higher than the vortex of fluid center pressure, helps more preventing high-velocity fluid, further avoid high-velocity fluid and slag washing away valve body sealing surface near valve body sealing surface.

Structural principle of the present invention:
The present invention includes valve body, Stuffing box assembly, bracket component, Handleset, screwed flange etc.The Stuffing box assembly comprises Stuffing box, filler, filler gland, Gland, valve rod; Valve rod passes the through hole of Stuffing box, between Stuffing box and the valve rod filler is housed, and the filler gland is installed in the filler top, and the cylindrical of filler gland cooperates with the Stuffing box endoporus, and the endoporus of filler gland cooperates with valve rod; Gland is installed in filler gland top, and the endoporus of Gland cooperates with valve rod; The Stuffing box assembly is installed on the valve body, and the counterbore of the cylindrical of Stuffing box and end face and valve body processing cooperates, diaphragm seal pad between Stuffing box and end face that valve body contacts.Bracket component comprises support, switch nut, switch screw rod, fluting Cock screw, lubricating cup, adjusting top power double-screw bolt; Support is installed in Stuffing box assembly top, and the endoporus of support and lower end surface cooperate with Stuffing box, and support is through being screwed into bolt and nut is fixed on the valve body, and Stuffing box is pressed on the valve body; Be fixed between support and the switch nut through the screw thread Cock screw that screws, slots between switch nut and the support, can prevent to occur relatively rotating between switch nut and the support; Switch screw rod and switch nut screw, and apply torque through handle, and the switch screw rod can be relative to switch nut upper and lower moving in rotation process; Lubricating cup is rack-mount, and the screw thread that screw for switch nut and support through lubricating cup adds lubricant oil; The screw of regulating top power double-screw bolt and support top screws, and the lower end cooperates with the counterbore of Gland, through rotation adjusting top power double-screw bolt, compresses filler gland and filler thereby can compress Gland, and packing seal is played a role.Between switch screw rod and valve rod, be connected with splitting chuck, the upper end of splitting chuck connects the switch screw rod, and the lower end connects valve rod, in the hole of the lower end of switch screw rod, roller is housed, and roller contacts with sphere on the valve rod.The endoporus of the collar cooperates with the cylindrical of splitting chuck, and two chucks cut open are fixed as an integral body, split chuck above circlip for shaft is housed, can stop the collar from split chuck, to be deviate from.The square hole of handle center cooperates with the square cylinder of switch screw rod, with nut and its moving axially on the switch screw rod of spacers; Through rotatable handle, can drive the rotation of switch screw rod.
Working principle of the present invention:
Through the handle that turns clockwise; Drive the rotation of switch screw rod; The switch screw rod is whole decline in rotary course, thereby drives valve rod and descend through splitting chuck, contacts and produce bigger impacting force up to the sealing surface of valve rod with the sealing surface of valve body; Thereby stop fluid to pass through, this moment, valve was a closed condition.
When being rotated counterclockwise handle; Drive the rotation of switch screw rod, the switch screw rod rises overally in rotary course, thereby drives the valve rod rising through splitting chuck; Thereby the sealing surface that makes valve rod breaks away from the sealing surface of valve body; Open the fluid passage, when valve rod rose to the extreme higher position, valve was a full-gear.
Filler in the Stuffing box through the effect of adjusting top power double-screw bolt, Gland, filler gland, thereby closely contacts with Stuffing box endoporus and valve rod cylindrical, can realize static seal and motive sealing.
